The 411.7 kilometre road, popularly known as Perimetral Norte ("north perimeter"), is primarily located in the Northern Brazilian state of Roraima, with other segments in Amazonas, Pará, and Amapá.
[1][2] The planning of the highway would consist of connecting Macapá, Amapá with the Brazil-Colombia border in the municipality of São Gabriel da Cachoeira, Amazonas.
The highway would have 2,454.7 km (1,525.3 mi) in total.
[3] In 1976, the highway entered the Wajãpi Indigenous Territory in Amapá.
The invasion was repelled by the indigenous leadership who expelled the intruders between the 1980s and the 1990s,[4] and therefore, the highway will probably never be completely built.
